Gastrocnemius medial head
The inner head of the superficial gastrocnemius muscle, behind the knee and upper calf.
Read the anatomy guide →Human anatomy · Right side
Study the lower leg in 3D, compare the tibia and fibula, and isolate selected front, calf and deep muscle structures.
Choose a step to select a structure and set the view. Some steps isolate it. Read the step-by-step guide →

Four muscles, different destinations. Compare foot movement with toe extension in these right-side guides. Sources checked; specialist anatomical review pending.
An anterior shin muscle that lifts the foot and helps turn its sole inward.
Read the anatomy guide →The long extensor directed toward the great toe; it also assists foot lift.

Compare longus and brevis on the right side, then contrast them with tertius in the anterior group. Sources checked; specialist anatomical review pending.
The more superficial lateral-leg muscle, with a tendon that continues beneath the foot.

Compare tibialis posterior and the two long toe flexors on the right side. This selected trio does not include popliteus. Sources checked; specialist anatomical review pending.
A deep posterior muscle directed toward the midfoot, rather than the toe tips.

The tibia is the larger, medial bone and carries most of the load through the lower leg. The more slender fibula lies laterally.
OpenStax · Bones of the lower limb ↗Anterior muscles help lift the foot, while posterior muscles help point it down. Soleus lies deep to gastrocnemius; tibialis posterior belongs to a deeper posterior group.
OpenStax · Pelvic and lower-limb muscles ↗Open Guided study · 3 steps above the model. Each button selects the matching structure on this side and sets a useful view. Isolated steps hide the other structures; Show context restores this region.
Highlight tibialis anterior with context retained. Compare its shape with the adjacent long bones.
Open Right tibialis anterior →Isolate soleus from the back. Restore context to see why it can be obscured by neighboring muscles.
Open Right soleus →Isolate tibialis posterior and follow the mesh toward its narrow distal end. This view does not include the foot bones around its attachment.
Open Right tibialis posterior →The tibia, fibula and thirteen muscle parts are loaded. Foot bones, plantaris, fascial partitions, retinacula, nerves and vessels are absent. Tendon portions retain the muscle color; they are not independently selectable.
